The upper portion'of each rear edge of theintermediate webs is forwardly inclined, as indicated at 8, so as topermit the ready insertion and entry of the follower between the rear ofthe cushioning mechanism and the interior face of the loop end of theyoke member. The upper edges of the vertical web 7 are joined by a topweb portion or flange. 9, said portion forming a horizontal closure wallfor the spaced hollow recesses or chambers 10 formed between saidvertical .rearwardly projecting webs 7 in the upper part of the casting.A bottom wall 11 extends rearwardly from the front wall 5, said bottomwall uniting .the lower edges of the vertical webs 7 and forming aclosure for the recesses or chambers 12 formed between said verticalwebs 7 and .adjacent the bottom of the casting:-

The rear wall 13 Vof the follower is arranged intermediate the top andbottom portions thereof, said rear wall-uniting intermediate portions ofthe rear edges of the rearwardly projecting vertical webs 7. Rounded .orcur-ved portions 141 are provided at the corners uniting the rear wallwith the outermost vertical webs, said curved portions being arrangedand adapted to lit within the rounded interior face ofthe yoke loopjoining the side arms ofsaid yoke, as shown in Figure 1. The rear wall13 constitutes a relatively large and effective bearing area contacting.the yoke whereby the drawing stresses are transmitted through the rearof the yoke to the cushioning mechanism and excessive loads transmittedto the Vcar underframing without cutting or otherwise mutilating theyoke. Y

Means is provided for bracing said Lbearing surface, said meansincluding the vertically arranged webs 7, thickened slightly, .as shownat 15, and a plurality of ytransverse horizontally disposed webs 16uniting the vertical webs 7 and the front and rear walls of the casting.A plurality of chambers or rectangular recesses 17 are formed betweenthe intersecting vertical and horizontal webs,`a series of transverselyarranged and substantially alined openings 18 being provided in thethickened wall portions 15 to light-en the casting and provide for therem val of the cores.

The follower is also provided with means at each side thereof forsupporting-.the rear end of the yoke in horizontal alinement and Contactwith the bearing surface, said means including projections 19arrangedupon the outermost vertical webs 7 adjacent the front wall ofthe follower and adapted to for-m seats for the side arms ofthe yoke.The upper surface of the projections are disposed substantially in ahorizontal plane passing through the lower edge .of the rear wall. Theprojections 19 on the :follower support the yoke, and the follower is inturn slidably mounted upon a plate 2O connected to the draft sills bymeans of the bolts 21. The plate is shown as extending under the rearfollower and under the rear end of the cushioning mechanism, and servesto support both of these elements of the draft rigging to permit theirsliding movement when'op erating in service. Openings 22 are preferably`provided in the front wall 5, said openings extending through to therespective up'` per and lower recesses or pockets 10 and l2 hereinbeforereferred to.

It will be apparent that by means of the internal flanges and-webs on .afollower con st-ructed in accordance with my present invention, one wall.is so formed as to provide a full and complete bearing surface withwhich a movable element of the draft' rigging may .cooperate withoutmutilation and that all stresses to which the associated parts may besubjected in service are amply resisted by sufiicientsections soeconomically arranged that the casting while pos-y sessing greatstrength is comparatively light in weight and is, moreover, a-vsimple.cast- .ing both to mold and cast.

The distance between the front and rear faces of the follower, thatis,the depth or .lil-ler distance between the outer surface' of the frontwall 5 andthe outer surface of the rear wall 13 is made to correspondwith the difference vbetween :the standard distance lof twenty-four andiive-eighths inches, required vbetween the rear end ofthe coupler buttand the front face of the draft yoke loop and the length of thecushioning mechanism be used. Before this distance was standardized, thedifference between it and the length yof the cushioning mechanism couldbe made so small that a simple solid follower plate', suoli vas shown at1.9 in the Patent No. 1,097,738 to Symington, could be used or, ifdesired, the fol-lower yplate or plates could be dispensed with. liliththe Standardization yof this distance, the problem of filling therelatively large space, when a short cushioning mechanism is used,without unduly adding .to the weight of the draft rigging, presenteditself. This has been satisfactorily lsolved by ,thje present device. y
